Biotechnological Products

Active_Yeast8260The character of wine is determined by a multifaceted interaction between grape type, fruit, climate, location, microbiological and winemaking technology used. The production of wines can be controlled through the application of biotechnological products such as active dried pure yeasts, lactic acid bacteria (Oenococcus oeni) and enzymes (bio-catalysts).


Yeast by SIHA

Active_Yeast4Eaton’s SIHA® active dried pure yeasts are specially selected from a variety of must samples and different types of wine. Their long standing practical experience and strict selection criteria they employ, offers you a specialized product that provides an individual solution for any type of wine. More than 500 different individual yeast strains are narrowed down to two or three strains that meet the highest SIHA® requirements for temperature tolerance, nutrients, foaming, low formation of acetaldehyde and much more. It is a natural selection process which takes 3-4 years. SIHA® offers selected specialized yeasts for individual demands.

Yeast Nutrients


Yeast nutrientA successful and complete alcoholic fermentation requires wine yeasts to still be alive at the end of the fermentation process because they are the essential interface between grape must and wine. Nutrients available in adequate and sufficient form ensure their survival.

When it comes to yeast nutrients, grape must ingredients are still somewhat of a mystery. Routine measurements of the sugar concentration and pH value and analysis of organic acids are useless for the purpose of yeast development. There is no correlation between the sugar concentration of a must and the nitrogen concentration (amino acid concentration), nor are essential yeast nutrients such as minerals, vitamins, fatty acids, and sterols analyzed. Legislators are trying to compensate this poor knowledge through an approval procedure for yeast nutrient preparations.

The correct choice of nutrients and timing of their application will guarantee optimum alcoholic and malolactic fermentation.

Pure, high dosage thiamine (thiamine dichlorhydrate) to improve the metabolism activity of yeast during alcoholic fermentation.

Malolactic Bacteria

SIHA Special Culture

The addition of lactic acid bacteria (Oenococcus oeni) for malolactic fermentation has become increasingly significant during the last decade, particularly for wine preparation. Previously known as second fermentation of the wine, modern oenologists use lactic acid bacteria specifically in the form of simultaneous inoculation or as a classic tool for inoculation after alcoholic fermentation.

Malolactic bacteriaThe key elements of malolactic fermentation are microbiological stability and harmonizing the flavor and the taste of the wine. Particular importance is placed on selecting the right lactic acid bacterial starter culture, which ultimately determines the sensory profile of the wine, and on the timing of inoculation. Adding the lactic acid bacteria directly (which is known as direct inoculation) guarantees a fast start and rapid cell proliferation, and forms the basis for optimal breakdown of L-malic acid into L-lactic acid to form secondary aromas that shape the desired style of the wine.

Inoculation Timing

  • In simultaneous inoculation, the lactic acid bacteria are added to the must at the same time as the yeast.
  • In fermentation inoculation, malolactic starter cultures are added halfway through the alcoholic fermentation process. However, the bacteria’s cell proliferation is strongly inhibited at this point due to the high metabolic activity of the yeast. Performing the inoculation at this time is therefore generally not recommended.
  • In post-fermentation inoculation, the lactic acid bacteria are added to the wine once the alcoholic fermentation process is complete.

Fining Agents by Eaton – SIHA Line

Fining260The term fining generally refers to products and process used to increase the shelf life of beverages. Fining agents refer to the removal of chemical haze (e.g. proteins) and biological haze (e.g. yeasts) or other suspended matter from the beverage. The products used for the wine and fruit juice sector are almost identical.



GelatineSIHA® gelatines are high-purity food gelatines for beverage fining. They have a high positive charge that reacts intensely with negatively charged beverage colloids, e.g. tannins and pectin residues and precipitates together with them.

Riddling Aids

Riddling Aids

Riddling aidSpecial products for improving the riddling characteristics of sparkling wine during fermentation in the bottle.

Riddling Aid Name


SIHA Brilliant Liquid

Riddling aid is a homogeneous colloidal suspension that improves the fermentation and agitation effect when champagne is fermented in the bottle. It prevents the yeast from sticking to the sides of the bottles (mask formation).

SIHA Tannin Liquid

Fining agent is a special homogeneous tannin solution extracted from gall nuts and edible chestnuts which is formulated for fining wine. The maturity and typical flavor of wine and champagne is positively influenced.

Activated Carbon

Activated Carbon

Activated carbonSIHA activated carbon is a high-purity activated carbon powder of vegetable origin used to correct color and odor deficiencies and off-flavors in beverages. Carbon is fine, black, lightweight powder used to remove unwanted color and odors from wine.

Fish Gelatin

Fish Gelatin

Fish gelatineSIHA® Isinglass Granulate is a white granulate produced from specially selected swim bladders of various species of large fish. Owing to their high positive charge they are particularly suitable for clarifying wine and beer.

Granulation of isinglass simplifies handling and dosage in wine and improves shelf life. SIHA Isinglass fining agent reacts quickly and intensely with negatively charged beverage colloids, leading to quick clarification of wine.

  • Excellent granulate distribution and rapid flocculation
  • Ideally suited for clarification of low-tannin beverages
  • Preliminary testing not necessary because SIHA Isinglass fining agent does not tend to over fining/underfining
  • Prepared from selected raw materials which are specially suitable for beverage fining



BentoniteSpecial products for the fining of beverages. They remove positively charged protein substances from musts, wines, fruit juices and vinegar.

Bentonite is a fine montmorillonite clay consisting of aluminum silicate anions (Al2O3.SiO2)(H2O)n neutralised by cations such as sodium, calcium, potassium and magnesium. Bentonite’s microscopic structure consists of many plates that position in such a way as to swell considerably when absorbing water. Bentonite has a negative electrical charge and is used to remove protein (giving “heat stability”).

Bentonite Name


NA-CA Bentonite

Special product for beverage fining and for removing positively charged albuminous substances from musts, wines, fruit juices and vinegar

SIHA Puranit™UF

Low sand Bentonite that was specially developed for ultrafiltration systems

SIHA® Active Bentonite G

SIHA® CA-Bentonite G

Special product for beverage fining, removes positively charged albuminous substances from wines, fruit juices, and vinegar

SIHA® Must Bentonite G

Fining agent from Eaton’s Begerow Product Line is particularly suitable for the treatment of grape musts

Silica Sol

Silica Sol

Silica SolSpecial silica sol of exceptional purity and activity for the fining of beverages. It is used in combination with gelatin or other positively charged fining agents as a flocculation intensifier.

Silica sol fining agent (BEVASIL® 30 or Levasil® 200/30% FG) is a transparent, slightly opalescent aqueous silicic acid solution and contains 30% colloid silicon dioxide (SiO2). The possibility of using the water insoluble, amorphous silicon dioxide as “aqueous solution” is achieved by colloid distribution.


The beverage treatment with silica sol fining agent and SIHA® Gelatin results in an economical and taste neutral clarification.

A taste improvement is also often attained. Even in difficult cases, the clarification of the beverage is accelerated; the turbidity deposit becomes more compact and beverage losses, filtration time and the use of filtering agents are reduced.

Deacidification Products by EATON – SIHA Line

DeacidificationIn cases where the climate leads to an acidic wine, an adjustment of the acid content is strongly recommended. The wine producer who handles this process carefully will be rewarded with harmonious, mild, and balanced wines. By stabilizing the microbiological, chemical and physical components of a beverage, you help their increase shelf life.

The tartaric acid content of wine fluctuates considerably from year to year and from area to area. Therefore Eaton generally recommends that you consult an expert before defining the method, time, and extent of deacidification. For specific and successful deacidification, the type and quantity of the acid constituents must always be known. It is best to ask for a full proposal to be prepared before proceeding with deacidification.

In practice, a multitude of factors that influence the method and stage of de-acidification have to be taken into consideration:

  • Total acid content
  • Tartaric acid content
  • Required de-acidification degree
  • Required tartaric acid content
  • Location of the company (local regulations!)
  • Character and flavour of the wine
  • Vine sort
  • Time specified for bottling the wine
